Older adults look at the ground more while they are walking than younger adults do. In the present study, the effect of blocking that exproprioceptive visual information on the walking pattern of older adults was investigated. The first 0.75 m of the floor in front of healthy young adults (n = 10, mean age = 26.0 years) and 2 groups of older adults (n = 10, mean age 65.7 years; and n = 9, mean age = 75.9 years) was occluded. The dependent variables were step velocity, step length, and step frequency. The effect of the manipulation on those kinematic variables increased with age. The older adults had a significant increase in velocity and step length. The possible use of optic flow information from the ground to regulate the velocity of self-motion is discussed.
与年轻人相比，老年人走路时看地面的次数更多。在本研究中，研究了阻断本体感觉视觉信息对老年人行走模式的影响。遮挡了健康年轻人（n = 10，平均年龄 = 26.0岁）以及两组老年人（n = 10，平均年龄65.7岁；n = 9，平均年龄 = 75.9岁）前方0.75米的地面。因变量为步速、步长和步频。这种操作对这些运动学变量的影响随年龄增长而增加。老年人的速度和步长有显著增加。文中讨论了利用来自地面的光流信息来调节自身运动速度的可能性。
